under 6.1.1r2 we use the cifs.netbios_aliases option to put more than 1 host name in wins. is there anyway to get a filer to show up in an nfs client with more than 1 host name? putting an alias in dns allows cmdline access thru that name, but of course, not in windows explorer.
thanks

DNS CNAME records, or multiple A records?
The NetBIOS Name Service has always had a mechanism by which clients can register names for an IP address; DNS hasn't always had that, and ONTAP supports NetBIOS Name Service registration, but doesn't support dynamic DNS.
I.e., the NetBIOS names associated with the appliance's address are under the control of the appliance; the same is not true of names obtained through DNS (or NIS), so there's nothing you can do *on the appliance* to support multiple host names for the appliance's IP address, you have to do it on whatever machines supply IP addresses for names (DNS server, NIS server - or client, if you're using a host file).
how is the filer's name broadcast as an nfs server?
our nfs client is integrated into windows nt explorer. in network neighborhood i see microsoft networks and nfs. when i open up the nfs servers list i see the filer's name.

nfs is not an "advertising" or "broadcast" service. that is, it does not jump up and down shouting "pick me" "pick me" "pick me".
it is a service to which you can connect. you have to know a name to which to connect. that name can be resolved to an IP number via DNS, NIS or local hosts files.

It's not. There is no mechanism, akin to the CIFS browser mechanism, by which an NFS server can announce its existence as an NFS server.
our nfs client is integrated into windows nt explorer. in network neighborhood i see microsoft networks and nfs. when i open up the nfs servers list i see the filer's name.
It's probably doing a hack similar to what the automounter does to implement "/net", such as broadcasting an NFS NULL operation (or a portmapper/rpcbind CALLIT operation for an NFS NULL operation) and collecting the results. Any reply is treated as an indication that the machine in question supports NFS; all it has in the reply is the IP address.
well the sw help says i can browse for nfs servers. so i guess it does something to look for them.
thanks for the responses.
